ABSTRACT:
An arm-actuated switch for a solid-state electronic watch having an electro-optic display. To conserve battery power, the display is normally quiescent and is momentarily turned on by the switch only when the wearer of the watch moves his arm in a particular way. The switch includes a pair of spaced contacts which when interconnected close the circuit. Such interconnection is effected by a shorting bridge formed by a pair of flexible tines which normally occupy positions adjacent to but out of touch with the contacts, the tines being flexed into engagement with the contacts by a pair of swingable mallets that are caused to swing and strike the tines only if the arm is moved in a predetermined manner.
